' 1 claim, 7 (cite-seal This invention reiates'to impro v e'ments inself propelled swathers;

An object of tlie inventionis to'provide'an improved self-propelled swather having its own' motor and provided with highaxles whereby the swath will readily passunder'themes it is fed from the middle df' 'the platform, thus preventing the doubling of'the fs'wath'when'afi'eld i'sstarted to be harvested.

Another object-of the invention is to provide an improved self propelled*swather having its; own motor for propelling the same, and'powe'r take-off means for actuating a pair of' tra'risversely, extending oppositelydispos'ed' drapers or endlessconveyors and a centrally disposeddraper or endless conveyor 'for receiving the cut grain from said'firstementio'ned dra'pers or endless conveyors for, discharging the swath centrally and vide an improved form of 'wheel supported Power, p

driven-harvesten-crswather which'will be highly efficient in operation and relatively inexpensive to manufacture and produce,

Withthe foregoing and other objects in View which will appear as the description proceeds,

the invention consists of certain novel details "of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes'maybe made in the construction and arrangement of parts without departing from the spirit of the .invention as claimed.

'Ealch'ot the front wheels I! "will be provided with separately controlled brakes olfiei ableby ie-make pedals 1i? and '25' to facilitate '"df the s'wather a tight are;

A substantially T-shaped draper or endless con veyor frame 22 is supported in front of the main frame by means of the bracing arms 23 and supporting arms 24 and 25 attached to and controlled by a hydraulic jack 26 and resiliently cushioned by means of the long springs 2! disposed at the opposite sides of the main frame.

The draper or endless conveyor frame 22 is formed with opposite ends 28 and 29 and guard boards 30' and 3|, and rotatably support the transverse reel supporting shaft 30 upon which the reel 3| is secured for rotation. The mounting for the reel supporting shaft 30 comprises the vertical brackets 32 secured to the ends 28 and 29 and the cooperating supporting arms 33 secured at 34 to said ends 28 and 29.

A cutter bar having teeth 35 is reciprocably mounted at the front edge of the draper or endless conveyor frame 22 and cooperates with the fixed cutter teeth 36 supported upon the transversely extending rail 31 directly below the reel 3|.

A clutch 38 and a pair of sprocket wheels 39 and 4!) are supported by the drive shaft between the motor 3 and the transmission casing 4, and the sprocket chains 4| and 42 are connected between the sprocket wheels 39 and 40 and the sprocket wheels 43 and 44 secured to the rear ends of the pair of power shafts 45 and 46 rotatably mounted in the bearing brackets 41 and 48, and 49 and 50 attached to the channel iron frame members I and 2. Chain tensioning sprockets 5| and 52 are supported by brackets 53 and 54 secured to the main frame members I and 2.

A universal joint '55 is connected between the drive shaft 53' extending forwardly from the transmission casing 4, and is connected with the shaft 51 which is connected with the differential gearing in housing 58: Oppositely disposed laterally extending shaft housings 59 and 60 are supported by the housing 58 and support the drive shafts 3| and 62, upon which the sprocket wheels 63 and 64 are fixed. Sprocket chains 65 and 66 extend about the sprocket wheels 33 and 64 and about the large sprocket wheels 61 and 58 secured to the large wheels 12 for driving 'the' same.

The central rear portion of the draper or conveyor frame 22 is formed with a rearwardly extending discharge chute 69 having side walls and H from which the swath is discharged centrally between the wheels l2 of the improved swather.

A pair of oppositely disposed drapers or endless conveyors 12 and 13 are supported in the outer ends of the conveyor supporting frame 22 for operation transversely of the frame 22, and moving inwardly when in operation. A centrally disposed longitudinally extending draper or endless conveyor 14 is positioned between the endless conveyors l2 and I3 and receives the grain after having been cut by the sickle bar teeth 35 and 36 and carried inwardly by the conveyors I2 and 13, then to be discharged as a swath from said conveyor 74. Pulleys l5 and 16 are attached to the inner ends of the endless conveyors 12 and 13 and are driven by the endless belts 11 and 18 which pass about the pulleys 19 and 89 on the forward ends of the power shafts 45 and 45.

A second pulley 8| on the shaft'46 drives an endless belt 82 which extends about the pulley 83 on the shaft 84 at the rear end of the endless conveyor 14.

The pulley 85 secured to shaft'46 drives an endless belt 86 which passes about the'pulley 81 4 on the inner end of shaft 88 mounted for rotation in the brackets 89 on the rear of the conveyor frame 22, and a sprocket wheel 90 on the outer end the shaft 88 is connected by the sprocket chain 9| to a sprocket wheel 92 on the end of the reel supporting bar 30 for driving the reel 3|. A sprocket wheel 93 on the shaft 45 supports and drives the sprocket chain 94, which in turn extends about the sprocket wheel 95 connected with the eccentric 96 to which the pitman rod 91 is connected. The opposite end of the pitman rod 91 is connected with a crank 98 on the shaft 99 rotatably mounted in the brackets 109 on the end 28 of the conveyor supporting frame 22. The

forward end of the shaft 99 is connected with the sickle bar for actuating the same.

'Iransversely extending U-shaped angle shoes 10! are secured to the bottom of the conveyor supporting frame 22 for reinforcing the same.

From the foregoing description, it will be apparent that there has been devised and provided a highly eirlcient form of self-powered and selfpropelled swather which may be used any place in a field in connection with a combine, and that it may be efficiently used next to fences and without having to make double swaths.

While the preferred embodiment of the instant invention has been illustrated and described, it is understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction may be resorted to without departure from the spirit of the invention. I

What is claimed is: V In a self-propelled swather, a frame and a cutter bar operating at the front of the frame, a U- shaped axle on the frame, supporting wheels mounted at the lower ends of the U-shaped axle, a drive shaft extending through the axle, sprockets secured to the ends of the drive shaft, stub axles extending from the U-shaped axle, sprockets secured to the stub axles, said wheels being mounted on the stub axles, chains operating over the sprockets of the drive shaft and sprockets of the stub axles, rotating the supporting wheels, endless conveyors mounted on the frame, a motor mounted on the frame means for transmitting power from the motor to the drive shaft and endless conveyors operating the drive shaft and endless conveyors.
